The People for the Ethical Treatment of Animals (PETA) is perhaps your best choice. Their website offers background information on dietary choices and why they should be made. Moreover, PETA is linked with a number of universities, celebrities, and researchers who actively engage in encouraging people to choose meat-free lifestyles.

Lastly, keep your eye open for articles by Colin Spencer, who has written extensively on the vegetarian lifestyle and veganism as a choice for a healthier life.
